How does Ciguatera work?

Ciguatera interferes with the normal function of nerve cells.

Are there safety concerns?

Ciguatera is UNSAFE. One bite of contaminated fish can be enough to cause symptoms. The most common symptoms include stomach cramps, nausea, vomiting, and diarrhea. Other symptoms include itching; numbness of lips, tongue, and throat; blurred vision; low blood pressure; slowed heart rate; alternating hot and cold sensations; and coma. In severe cases, shock, muscular paralysis, and death can occur.

Ciguatera poisoning can be caused by eating normally safe, bottom-feeding, coral-reef fish that have collected a poison from the food chain. It is common in areas of disturbed reef, including waterfront construction. Over 400 normally safe fish species may contain toxin, with the red snapper, barracuda, and grouper most often involved. Florida and Hawaii have the greatest incidence of ciguatera poisoning. These fish appear normal, including smell and taste. There are no good "rules of thumb" for detecting poisonous fish.

Do not use ciguatera if:
  • You are pregnant or breast-feeding.

Dosing considerations for Ciguatera.

The appropriate dose of ciguatera depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for ciguatera. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
